Euch linerM has en interior steamohinnhor which is provided with iin inlet machine and extends from one sidv to thvnro six series oi hammers D D on enohshai't ICO frame is a bracket K, supporting a transverse l 1 nlatmwhlch extends across the machine bet- Ween the corrugated liner M and the grate bars G. This plateiprevents material from dropping down through the space which would otherwise be lett open. l

The bars H', together with their connections H and H3, tarnish equalizinggbars for clamping the gratebars in position against the frame and the central bloeit E.

ilisaxnnin` the shafts to he driven in the direction of t e arrows shown in Fig. 2, then if the material be inserted through the hopper A3 auch material will fall in the path or the hammers D and be crushed between the said hammers, which are driven at a very high rate of speed. Ahammer on one shin" t maybe considered as one of a pair ci hammers, the other member of which pair is a corresponding hammer on the other shaft. The 1n aterial drop )ed through the hopper A3 is therefore crushed between a pair of hammers, and this crushing is accomplished by virtue of a very great velocity given to the hammers. The hammers D are provided with slots D2,

' by means of which they are connected to the rods C. By this means the hammers are permitted when striking large or hard pieces ,itoyield radially with respect to the shaft B its well ae circumferentially with respect to their pivoting-rods C. The crushed material drops downward, being arted by the central block E, so that part or it moves toward one end of the machine and the other part toward the other. That which is line enough drops through the grate-bars G and through the bottom of the machine into a suitable receptacle, which would he within the foundation upon which the machine was placed. Mate rial too coarse to pass through between the grate-bars is driven around by the hannncrs and comes into the path of the new material being inserted through the hopper A. ln passing' around some portions of this material nre broken on the corrugated plate M and Sonie of it is broken only when thrown in thc path of the hammers revolving in the adjacent cylindrical chamber. As the hannncrs wear b` use theymay be adjusted outward, us oxil ained by the operation ot the eccentric t?" and the shaft C, upon which the lunnnn-rs are pivoted.

In caseswhere it is desired to sometimes crush material so as to leave it coarse l cut the frame in two transversely, and thc block E also, so that the two cylindrical chambers may be moved from each. other. The space oratori left openbj' niotingtheparts from each other is lilled for the block by a liner El (shown in Fig. Q) and for the trame by a. similar liner E4. The two portions are then secured together by bolts A for the lower portion of the frame and A in the flanges A5 for the covers A.
